ASUS' TUF (The Ultimate Force) line of extra-durable motherboards will include two socket LGA1150 models, the Z87-Sabertooth, and the Z87-Gryphon. The more familiar-sounding Z87-Sabertooth, is built in the conventional ATX form-factor, featuring an 8-phase CPU power supply, thermal armor covering most parts of the board, dust-covers or dummy-spacers for most ports, slots, and headers, yet an active fan-based air-circulation within the thermal armor. Connectivity includes eight SATA 6 Gb/s ports, three PCI-Express 3.0 x16 slots wired to the CPU, 8-channel HD audio, gigabit Ethernet, eight USB 3.0 ports, HDMI and DisplayPort outputs, and a number of conventional USB 2.0/1.1 ports.

The Z87-Gryphon is the first micro-ATX motherboard in the TUF series, featuring an optional thermal armor kit, 8-phase CPU power, expansion slots that include two PCI-Express 3.0 x16 (x16/NC or x8/x8), a PCI-Express 2.0 x16 (electrical x4, wired to the PCH), six SATA 6 Gb/s ports, four USB 3.0 ports, 8-channel HD audio with optical SPDIF output, gigabit Ethernet, and display outputs that include DVI and HDMI.

I like the mATX version. Ideas coming to mind.
But still same problem for the Z87 board fan. 35mm, not easy to find replacements. 40mm would have been better, as there is many good ones out there. The I/O side, can fit 40mm already.
